Use winter tires if you live and drive in real winter conditions during the winter season. You can then choose between studded or non-studded tires as your winter tire choice. Both are excellent in winter condition regardless of snow or ice.
Choose studded tires if you will be driving on a lot of ice and packed snow. The studded tires will give you the best grip on these surfaces.
Choose non-studded tires if you will face mainly snow and if there are limitation related to studded tires.
Choose an all-weather tire if you want to stick with one tire for the whole year, regardless of weather conditions. If they are winter-approved, the weather will not matter.
